Up near the top of the dead tree, a pair of pine martens had made their den in the hollow trunk, and reared a family of young martens that drew Kagax's evil thoughts like a magnet. The marten belongs to the weasel's own family; therefore, as a choice bit of revenge, Kagax would rather kill him than anything else. A score of times he had crouched in this same place and waited for his chance. But the marten is larger and stronger every way than the weasel, and, though shyer, almost as savage in a fight. And Kagax was afraid.

But to-night Kagax was in a more vicious mood than ever before; and a weasel's temper is always the most vicious thing in the woods. He stole forward at last and put his nose to the foot of the leaning tree. Two fresh trails went out; none came back. Kagax followed them far enough to be sure that both martens were away hunting; then he turned and ran like a flash up the incline and into the den.

In a moment he came out, licking his chops greedily. Inside, the young martens lay just as they had been left by the mother; only they began to grow very cold. Kagax ran to the great spruce, along a branch into another tree; then to the ground by a dizzy jump. There he ran swiftly for a good half hour in a long diagonal down towards the lake, crisscrossing his trail here and there as he ran.

Once more his night's hunting began, with greater zeal than before. He was hungry now; his nose grew keen as a brier for every trail. A faint smell stopped him, so faint that the keenest-nosed dog or fox would have passed without turning, the smell of a brooding partridge on her eggs. There she was, among the roots of a pine, sitting close and blending perfectly with the roots and the brown needles. Kagax moved like a shadow; his nose found the bird; before she could spring he was on her back, and his teeth had done their evil work. Once more he tasted the fresh brains with keen relish. He broke all the eggs, so that none else might profit by his hunting, and went on again.

On some moist ground, under a hemlock, he came upon the fresh trail of a wandering hare—no simple, unsuspecting mother, coming back to her babies, but a big, strong, suspicious fellow, who knew how to make a run for his life. Kagax was still fresh and eager; here was game that would stretch his muscles. The red lust of killing flamed into his eyes as he jumped away on the trail.

Soon, by the long distances between tracks, he knew that the hare was startled. The scent was fresher now, so fresh that he could follow it in the air, without putting his nose to the ground.

Suddenly a great commotion sounded among the bushes just ahead, where a moment before all was still. The hare had been lying there, watching his back track to see what was following. When he saw the red eyes of Kagax, he darted away wildly. A few hundred yards, and the foolish hare, who could run far faster than his pursuer, dropped in the bushes again to watch and see if the weasel was still after him.

Kagax was following, swiftly, silently. Again the hare bounded away, only to stop and scare himself into fits by watching his own trail till the red eyes of the weasel blazed into view. So it went on for a half hour, through brush and brake and swamp, till the hare had lost all his wits and began to run wildly in small circles. Then Kagax turned, ran the back track a little way, and crouched flat on the ground.

In a moment the hare came tearing along on his own trail—straight towards the yellow-brown ball under a fern tip. Kagax waited till he was almost run over; then he sprang up and screeched. That ended the chase. The hare just dropped on his fore paws. Kagax jumped for his head; his teeth met; the hunger began to gnaw, and he drank his fill greedily.

For a time the madness of the chase seemed to be in the blood he drank. Keener than ever to kill, he darted away on a fresh trail. But soon his feast began to tell; his feet grew heavy. Angry at himself, he lay down to sleep their weight away.
